Specification of Letters Patent Patented Oct. 27, 1908.

Application filed May 24, 1307 Serial. No. 376,478.

To all ill/mm it imp concern:

Be it known that l, Cmus'rnuv .llAvns'mm',

as the lion ting suction chau'lbcr adapts itself to the various waterlevels which a stationof Vi ilmcrsdorf, a subject of the King of arychamber is not capable of and it has the Pro L121, and whose post-other:address No 15;.) Bel-linorstrasse, \Vihnersdorf, near Berlin, Prussia,German Empire have invented new and useful. Improvements in Devices forlflxhausiziug Air from Siphons of Sluices and the Like, of which thefollowing is a specification.

The invention. relates [0 means for removing the air frcm eiphons suchas are used for this purpose, the water contained therein 3 being letoil into the lower level of the sluice so as to obtain in the chamber orin the bell the necessary space for the air to be removed from thesiphon. These stationary suction chambers however have the disinivantaithat a water column. must remain between the air in the suction chamberand the atnn'lspnerc of a height equal to the dillcrence h pressurebetween the pressure in lhe chamber and the ahnospheric pressure. It. istherefore necessary to arrange the stationary suction chamber at as higha level as possible. lllovable slntion bells ln'n'c then forc alreadybeen employed for exhausting the air from siplibns iii-slums or llKiliH.lo obtain the space ncccs ary for the air rcmoved from the siphon. Themechanical means however employed for raising or lift ing such movablebells for the purpose aforesaid required power cspm-ially if the raisingis to be effected quickly, the lower incrcas' ing according to theincl-ens 1g attenuation of the air.

According to the n-esent invention float ing suction chamber iscn'iployed for enhausting the air from siphous of slunrm, reservoirs andthe like, 2'. c. a suction chamber which is provided with one or moreoul let or discharge pipes and is connected up to the suction conduit01' the siphon and the clnuulmr not being slatlonarv but rigidlyconnected with a floating chamber or casing so ihat it li0ats freely inthe water. being nnlded vertically in a similar manner to :i gascollecting bcll. This floating suction chamber hasilibe adwoita rc thatit enables siphon locks to' be used for siluiccswifh considerablyfluctuating falls such sea sluiccs,

further advantage as compared with the mechanically raised suctionbells, that it re quires no special external power for rais ing it.

The accompanying drawings illustrate two modes of carrying out theinvention.

Fi ulrcs 1 and SllOW in section and in two different positions a simpleform of suetion chamber which is lillcd from the lower portion or levelof the sluice by means of only one discharge pipe. Fig. 3 shows insection another forum having two discharge or flow ell" pipes which nntybe closed if the motion chamber to be filled from the upper part of thesluice.

In carrying out the invention according to one mode as illuslraleil byFigs. 1 and 2,

, the suction chamber, 4/, is rigidly connected with a closed floatingchamber or casing, b,

i by moons of a framcivorlo r, or the like and connected with deep waterby means of one discharge pipe, j', although more than one may be used.Guide rails, c, are ar ranged. on the supporting or side walls, is, thechamber, in and the floatingchamber or casing, a, being guided up anddown thereon by means of rollera, 1 in a similar manner to a gascollecting bell. (Z, is the suction pipe leading to the sluice siphons.The vertical part of the pipe, (I, works in an air tight stalling box,0', leading to the suction chamber, a.

In the position. shown in Fi 2- the tank a is filled, the pipe. isclosed by means of a known suitable distributing device such as a.three-way cock or the like (not shown in. the drawings) against theatmosphere. Vv'ilbin the said pipe "I in the said position of thechamber a is a partial vacuum. NVithin llie. siphon is atmosphericpressure, so llml \i lTPn by means of the said distributing device lhcpipe 4/ is opened for connecting the chamber a with the siphon, airpasses from 'lhc latter into the said chamber (1', thereby displacingthe water from the chamber through pipe f. The chamber a and thefloating chamber 7) are raised corresponding with such displacement ofWater until the clmmbor is completely, emptied and reaches its highestposition, as shown in Fig. 1. A Watcr column stands in the dischargepipe f balancing the partial vacuum in the chamber a.

W'ithin the siphon the overflow of air into the chamber (1 effects adiminution of pres- 5 sure of the remaining air. In consequence theatmospheric pressure lifts the water in both legs of the siphon. As soonas the water in the le connectcd with the upper level or pond o? thesluice has reached the ridge of the siphon and flows over into the otherleg connected with the under level or pond of the sluice, the air yetcontained in the siphon is taken away and the siphon is completelyfilled with running water. In conse uence the air in the chamber a issucke off through the pipe at and water enters from the under sluicelevel through the discharge-pipe f and fills the chamber a. Now thechamber a together with the floatin chamber 6 sinks again. For theinitial fllfing of the chamber a, a suitable air pump can be used forsucking off air from the pipe cl and the chamber a. After the chamber ahas been filled and a partial vacuum has been produced in said pipe d,the latter is closed against the atmos here 1n the manner described. Butprefera ly an arrangement is provided for making the initial fillingfrom the u per level of the sluice, as shown in Fig. 3 o? the drawings.

In the form of construction shown in Fig. 3 two dischar e pipes, f, areprovided which may be'close by means of valves, h,.if the tank orchamber, a, is intended to be filled, from the upper level by means of aspecial filling connectiorifll, the chamber, a, being connected in thiscase with the upper part of the ,sluice by means of a flexible conduitsuch as a hose j, or the like-provided with a corresponding connectingpiece.

For the purpose of initial filliii and prodncing a partial vacuum withint e pipe 01, the valves h are closed and the valve 2 of the hose jopened. Before the chamber a has against the atmosphere. Then the, valve71 isv c osed and the valves k are opened. Now

the apparatus is in the condition as shown in Fig. 2 and its function isas referred to.
